added ssaa and efb scale as separate configurations:

Browse Source 
efb scale :
auto fractional: the original scaling way, will grant a 1:1 pixel mapping between efb and screen giving the best image quality even in non standard resolutions
at the cost of glitches in some games.
auto integral: automatic but only int values for the scale, no glitches but only the correct pixel scaling when using some resolutions.
the rest are the fixed scales.
enjoy.
